Actinic keratoses (AKs) are pink or skin-colored patches on the skin that occur after years of sun and UV exposure. They are extremely common among the adult and elderly populations and often occur on the face, scalp, neck, ears, shoulders, and arms.
AKs are scaly or rough to the touch and can range in size from a few millimeters to an inch in diameter. Some AKs may even form “horns” as they grow. Although they are slow-growing, AKs are considered a type of “pre-cancer” and if left alone, can potentially turn into skin cancer. However, because they are superficial skin growths, AKs can easily be removed using cryotherapy (liquid nitrogen).
AKs may be common, but they are also preventable. To stop the growth of AKs in the future, try to limit excessive sun exposure and regularly use sunscreen of SPF 30 or higher when in the sun for prolonged periods of time.
